Tailback Marcus Thigpen, who was used as a slot receiver last year, has apparently returned to that role. Thigpen's scrimmage snaps were as a receiver…. Cornerback Dimitri Patterson started Monday night's scrimmage, replacing Richard Marshall as the cornerback paired with Brent Grimes….Josh Samuda appears to be getting a full-time tryout as the starting left guard. Nate Garner replaced him as the backup center and rookie Dallas Thomas was on the second-team line….TE Michael Egnew and WR Brandon Gibson both dropped possible touchdown passes from Tannehill.
